Abstract

T\cal T-parity in the Little Higgs model could be violated by anomalies that allow the lightest T\cal T-odd AHA_H to decay into ZZZZ and W+WW^+W^-. We analyze these anomaly induced decays and the two-particle and the three-particle decay modes of other heavy quarks and bosons in this model which yield unique Large Hadron Collider (LHC) signals with fully reconstructable events. T\cal T-odd quarks in the Little Higgs model are nearly degenerate in mass and they decay by almost identical processes; however, members of the heavy Higgs triplet follow distinct decay modes. The branching fractions of three-body decays increase with the global symmetry-breaking energy scale ff and are found to be at the level of a few percent in heavy quark decays while they can reach up to 10% for heavy bosons.
